MelissaRelatorios: chart + tabela 50/50 + min-height mobile

Wrappa "Sessoes por mes/semana" e "Sessoes no periodo" em .mr-charts-row
flex 50/50 lado a lado em desktop. Mobile empilha (column) e a tabela
ganha min-height: 360px pra nao colapsar pra ~50px em telas curtas.
Chart wrap/skel viram flex: 1 dentro do card-chart pra acompanhar a
altura compartilhada da row.
